in fibrous joints, the bones are joined by the collagen fibers of connective tissue; fibrous joints are ___
immovable
in cartilaginous joints the bones are united by cartilage; cartilaginous joints are ___ ___
semi movable
the two types of cartilaginous
joints are:
___drosis
___physis
synchondroses
symphysis
the three types of fibrous joints are:
sutures
gomphoses
syndesmoses
connects bones with hyaline cartilage
SEMI MOVEABLE
___droses
synchondroses
the body of one bone meets the body of another
SEMI MOVEABLE
___physis
symphysis
in synovial joints the articulating bones are separated by a fluid-containing joint cavity; synovial joints are ___ ___
freely movable
the six types of ___ joints are:
1. hinge joints
2. ball and socket joints
3. condyloid joints
4. pivot joints
5. planar joints
6. saddle joints
FREELY MOVABLE
synovial
___ are fluid-filled sacs that cushion and protect the body’s joints and muscles, reducing friction and wear and tear
bursae
a ___ ___ is a layer of connective tissue that protects tendons and helps them move smoothly
tendon sheath
when ___ ___ are large and fit snugly together, or when the socket is deep, synovial joint stability is improved
articular surfaces
the ___ of synovial joints unite the bones
and prevent excessive or undesirable motion; the more of this a joint has, the stronger it is
ligaments
the muscle tendons that cross the synovial joint are kept stable by the ___ ___ ___ ___
tone of their muscles
hyperextension, extension, & flexion are ___ ___ allowed by synovial joints
body movements
the ___ ___ connects your lower jaw to your skull, located in front of each ear
temporomandibular joint (TMJ)
(tem·pr·ow·man·di·byuh·lr)
the ___ ___ is stabilized by the rotator cuff muscles that attach to the joint capsule
glenohumeral joint
(shoulder joint)
ligamentum teres
(ligament of the head of the femur)
oblique popliteal ligament
arcuate popliteal ligament
the ___ is a C-shaped piece of cartilage in the knee that acts as a shock absorber and helps stabilize the knee
meniscus
is from the ancient greek word meniskos meaning “crescent”
___ is a painful condition that occurs when one or more bursae become inflamed
bursitis
___ is a painful condition that occurs when a tendon becomes inflamed
tendonitis
in a sprain, the ___ reinforcing a joint are stretched or torn
ligaments
ligaments connect ___ ___ ___
bones to bones
tendons connect ___ ___ ___ or other structures
muscles to bones
